note 73468 added to function.preg-match

Concerning note by warcraft at libero dot it , 20-Jul-2006 07:29. The proposed code for checking the "codice fiscale" (italian fiscal ID) could rule out valid submissions. Indeed, issued "codici fiscali" may be modified by the goverment in case of persons with same name birthday and birthplace, by turning one or more of the seven numbers into letters respecting the correspondence 0123456789 - LMNPQRSTUV. Hence the correct code to check a submitted "codice fiscale" is the following modification of warcraft's code: $cf='/[a-z]{6}[0-9lmnpqrstuv]{2}[abcdehlmprst][0-9lmnpqrstuv]{2}'._ '[a-z][0-9lmnpqrstuv]{3}[a-z]/i"; return preg_match($cf,$var); namely: - there are 16 characters - characters at positions (count start from 1) from 1-6, 9, 12 and 16 are in [a-z]; - all other characters are in [0-9lmnpqrstuv] Gherardo ---- Server IP: 69.147.83.197 Probable Submitter: 80.183.226.202 ---- Manual Page -- http://www.php.net/manual/en/function.preg-match.php Edit -- https://master.php.net/note/edit/73468 Del: integrated -- https://master.php.net/note/delete/73468/integrated Del: useless -- https://master.php.net/note/delete/73468/useless Del: bad code -- https://master.php.net/note/delete/73468/bad+code Del: spam -- https://master.php.net/note/delete/73468/spam Del: non-english -- https://master.php.net/note/delete/73468/non-english Del: in docs -- https://master.php.net/note/delete/73468/in+docs Del: other reasons-- https://master.php.net/note/delete/73468 Reject -- https://master.php.net/note/reject/73468 Search -- https://master.php.net/manage/user-notes.php
